(PVs) are arrays of cells containing a Solar photovoltaic material that converts solar radiation into direct current electricity. Materials presently used for photovoltaics include monocrystalline silicon, polycrystalline silicon, microcrystalline silicon, cadmium telluride, and copper indium selenide/sulfide.
When optical lens size is compatible with the working wavelength, the traditional lens analysis tools such as ray-tracing method will lose their accuracy. The FDTD method can be used to advantage in the nano-lens simulation. OptiFDTD software also provides tools so that beam focus size, focus distance, and far-field transform can be obtained directly.
Biological cells can be considered as dielectric objects with a given refractive index distribution. Light scattering simulations provide us with an efficient tool for studying cell morphology as well as the nature of scattering and its sources.
Optical gratings are basically periodic layouts that may contain chirp or apodization. The wave inside the grating may be complex: Scattered field, transmitted field, diffracted field are all exist, which demand more advanced simulation tools for highly accurate results.
This example illustrates a high contrast ridge waveguide with PBG air holes drilled in the waveguide. The PBG has a defect in the center which will lead to resonance in the wave propagation.
Finite-Difference Time-Domain (FDTD) is a powerful, highly integrated and user-friendly software application that enables the computer-aided design and simulation of advanced passive and non-linear photonic components. FDTD enables you to design, analyze, and test modern passive and nonlinear photonic components for wave propagation and the nonlinear phenomenon.
